Ultra Wideband (UWB) Microstrip Patch Antenna with Adjustable Notch Frequencies

Abstract

An ultra-wideband (UWB) antenna capable of producing notches at lower frequencies of the UWB band is presented in this paper. The notch can be adjusted to attain desired frequency by changing the size and the distance between the two studs placed between the circular patch. Defected ground structure has been applied to improve the antenna performance. The VSWR and radiation plots approve the suppression of the desired notched frequency.
